🏴:you were his first on everything, first love and his first kiss, unfortunately your family suffered a great deal of bankruptcy on your father's business causing your family to run to the Graysons for help.

Specifically you.

You went to Liam asking for help but he turned you down colder than ice, it was a selfish reason and now you two are enemies, after a lot of begging, you finally got a job as Isaac's personal assistant and it is safe to say that...

...Liam doesn't want anyone near what's his, especially his own brother.
